This bug has been fixed in Release 2006b (R2006b). For previous product releases, read below for any possible workarounds:
We have verified that there is a change in the behavior in Simulink 6.2 (R14SP2) in the way that the above warning is produced when using MODEL command.
To workaround the issue, you can safely ignore the warning or edit the line containing the MODEL command to include the command's last ('flag') argument as shown below:
f14
feval('f14',[],[],[],'lincompile');
[sizes,x0,xstr] = f14([],[],[],'compile');
